Abstract
The utility model discloses a connection rod for a large-size transportation vehicle. The connection rod comprises a connection rod body and a connection end part of the connection rod body, wherein a fork-shaped slot for enabling a flat connection rod head part to be inserted is formed in the middle of the connection end part; pin shaft holes for enabling pin shafts to be inserted are transversely formed in two side edges of the fork-shaped slot; the two side edges of the fork-shaped slot are circular side plates; symmetric planes are arranged on two sides of each pin shaft hole of each circular side plate; the slot bottom of the fork-shaped slot is an arc bottom surface formed by taking the shaft centers of the pin shaft holes as centers; a threaded hole which is in threaded connection with the connection rod body is formed in the other end part, which is opposite to the fork-shaped slot, of the connection end part; low-alloy steel anti-abrasion blocks are embedded into the inner side walls of the two side plates of the fork-shaped slot, are embedded into the inner side walls of the peripheries of the pin shaft holes and are flush with the inner side wall surfaces. The connection rod disclosed by the utility model has the characteristics of improving the abrasion resistance of the integral structure, enhancing the power transmission effect and the like along with simplicity in structure and convenience in use and mounting.
Description
Technical field
The utility model relates to a kind of connecting rod for large-scale haulage vehicle, belong to power transmission technology field.
Background technique
Power transmission mechanism in existing large-scale haulage vehicle, need to there is connecting rod to carry out transmission of power and connection, the connecting ball head of connecting rod end wherein connecting rod by bearing pin loose joint, because the relative connecting ball head of connecting rod exists relatively rotating of certain limit, can rub with the sidewall of connecting ball head unavoidably, produce wearing and tearing, therefore, not only the connection part wear-resisting property of connecting rod will be got well, the connecting ball head that contacts in contrast and produce wearing and tearing also needs to have good high-abrasive material to make, moreover, the structural strength of increase connecting ball head is also most important; This prior art is existed to obvious deficiency.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of simple in structure, easy to install and use, can improve integrally-built wear-resisting property, improves the connecting rod for large-scale haulage vehicle of transmission of power effect.
The purpose of this utility model completes by following technical solution, described connecting rod comprises the connection end of a connecting-rod body and connecting-rod body, the centre that it is characterized in that described connection end offers the forked type groove inserting for flat-shaped link rod head, the dual-side of forked type groove is horizontally arranged with the pin shaft hole of pegging graft for bearing pin, the dual-side of described forked type groove is that circular side plate forms, the pin shaft hole both sides of described circular side panel are provided with symmetrical plane, and the bottom land of described forked type groove is the circular-arc bottom face forming centered by pin shaft hole axle center.
On the other end of the relative forked type groove in described connection end, be provided with the tapped hole that connecting-rod body screw thread spins, on the madial wall of described forked type groove biside plate, be embedded with low alloy steel wear-resistant block, and this wear-resistant block is embedded in the madial wall of pin shaft hole periphery, concordant with interior sidewall surface.
The utility model belongs to the one improvement to prior art, and it has simple in structure, easy to install and use, can improve integrally-built wear-resisting property, improves the features such as transmission of power effect.
